IMPROVEMENT IN IRON LINING S FOR FIRE-POTS.

The Schedule referred to in these Letters Patent and making part of ..tl1e same To all whom it may concern:

Be it known that I, EDWARD A. Terran, of Williamsburg, in the county of Kings and State of New York, have invented a new and useful Improvement in Iron Block-Lining for Fire-Pots; and I' do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawing forming part of this specification.

Figure 1 is a front view of one of my improved iron blocks for lining fire-pots. 4

Figure 2 is a vertical section of, the same, taken through the line a; x, fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish improved iron blocks for lining the firepots of stoves, heaters,

' furnaces, 8w. and

It consists in the iron ribbed or recessed blocks, made in the general form of fire-brick, so as to be placed in and fit. into the fire-pot, in the manner of fire-brick, as hereinafter more fully described.

A represents the blocks, which are cast of a breadth, height, and general formof fire-brick; that is to say, of such a form and size the form and size of the firepot into which the said blocks are to be placed may require. This construction of the lining guards it from being cracked by the heat, as each block A can expand or contract as the heat contiguous to it mayafiect it. The plate that forms the back of the block A is made with inwardly-projecting flanges, a, along its top, bottom, and side edges, and with horizontal or vertical cross-ribs, a, across its face, as shown in figs.

l and 2, the face of the block A thus presenting a series of deep recesses, in which the ashes lodge, and protect the iron from the intense heat of the fire.

The forward edges of the flanges a and ribs to being narrow, present only a small surface to the coals,

so that-clinkers will not adhere to them.

The upper parts of the blocks A, where the heat 7 will not be so intense, may be made thinner than the block being made to correspond ill shape to the internal form of the fire-pot, as set forth.

The above specification of my invention signed by me this 7th day of February, 1870.

EDWARD A. TUTTLE.
